The Incredible Hulk, Vol. 1

Bruce and Rick head out into the desert, creating a secure chamber in an underground cavern they can use to contain the Hulk come nightfall. Before they can use it, however, the Toad Men from space use their magnetic powers to capture them. Rick is released, but they keep Bruce Banner for his scientist's mind. Banner becomes the Hulk and escapes, but when the military finds the captured ship, with only Banner aboard, they accuse him of being a traitor. Banner escapes confinement when he becomes the Hulk, and once free, he manages to locate a military weapon that he uses to single-handedly defeat the alien invaders.
